Manifest merge by sequence · case 03
Appending a refreshed manifest duplicates overlapping sequence numbers.
Case contract
Merge unique-per-input [integer media-sequence,payload] records by sequence; incoming revisions win, output is sequence ordered.
Why this case matters
A deterministic local media controller stage; metadata and downloaded data are supplied explicitly. No external player, service or codec is required.
One recorded failure
